IMPROVEMENT IN MACHINES FOR POLISHING OIL-CLOTH.

Specification forming part of Letters Patent No. 162,440, dated April 20, 1375; application filed July 30, 1874.

To all whom it may concern Be it known that I, JosIAH WEBBER, Jr., of Elizabeth, in the county of Union and State of New Jersey, have invented an Improved Pumicing-Machine, of which the following is a specification:

My invention relates to a machine for pumiciug or polishing the surface of enameled cloth and other fabrics; and it consists in the combination of a card-clothed or rough-surfaced cylinder, a pumicing-cylinder, a pair of stretching-bars, and two or more beams or rollers for winding the cloth, all arranged and operating in the manner and for the purpose hereinafter particularly described.

In the accompanying drawing, Figure l is a longitudinal section ot' my improved machine. Fig. 2 is a top View.

The frame-work A which supports the working parts may be of any suitable form and construction, having at one end two standards, a, at which end is journaled a cylinder, B, the surface of which is covered with cardclothing, or is otherwise roughened. In the upper portion of the standards a are pivoted the upper ends of two rods, c c, in the lower ends of which is journaled a beam or roller, C. At the end of the frame opposite the standard is journaled a beam or roller, D, similar to that journaled in the rods c. On the upper side of the frame, transversely thereof, are secured two bars, E E, on the upper sides of which are teeth or notches e, inclined from the longitudinal center outward and toward the end of the frame where the cylinderB is `journaled. Between the bars E E is secured a similar bar, EX, with similar teeth or notches formed on its lower side. On

the upper side ot' the frame A, between the standards a and the bar E nearest thereto, is journaled the pumicing-cylinder G, to the surface of which is attached a number of' lags, g, which may be of stone, emery composition, or any suitable material coated with pumice or other polishing substance. The cylinders B and G are provided with driving-pulleys, and both revolve in the same direction, but at different rates of speed, the pumicing-cylinder G traveling much faster than the cylinder B. The cloth or fabric H to be operated upon is wound upon the beam or roller D. The free end of the cloth is passed under the bar EX, over the bars E, under the cylinder G, and over the cylinder B, and is attached to the swinging beam or roller C. As the machine is operated, the card-clothed or rough-surfaced cylinder draws the fabric through the machine, and, by its friction, causes the roller C to revolve and wind up the fabric, while lthe pumicing operation is performed by the cylinder G.

I do not claim, broadly, the use ot' the stretching-bars E EX, as l am aware that simi- Witnesses HENRY T. BROWN,
